Answer:
see below
Step-by-step explanation:
Use the distributive property to eliminate parentheses. Remember that the product (-1)(-1) is 1.
a-(1-b)+1 = a -1 +b +1 = a + b . . . . this one
__
-(1-a)-b+1 = -1 +a -b +1 = a - b
__
(a-1)-(b-1) = a - 1 - b + 1 = a - b
__
a-(-b-1)+1 = a +b +1 +1 = a + b + 2
Answer:
Therefore the cost of a bag of chips is $0.75
therefore the cost of a cheeseburger is $3.
Step-by-step explanation:
i) let the cost of a cheesburger be x.
ii) let the cost of a bag of chips be y
iii) therefore it is given that x + y = 3.75
iv) it is also given that 2x + 3y = 8.25
v) multiplying the equation in iii) by 2 we get 2x + 2y = 7.50
vi) subtracting the equation in v) from the equation in iv) we get y = $0.75
vii) Therefore the cost of a bag of chips is $0.75
viii) Substituting the value of y found in vii) into iii) we get x = 3.
ix) therefore the cost of a cheeseburger is $3.
It would be y=-1/3+1

Answer:
1. 1072.6
2. 753.6
3. 194.2
4. 59.5
5. 4848.3
6. 1818.3
Step-by-step explanation:
We have to use the trigonometric functions sin, cos, and tan. Remember the mnemonic SOH-CAH-TOA when solving these problems. (sinθ=opposite/hypotenuse, cosθ=adjacent/hypotenuse, tanθ=opposite/adjacent)
1. tan(40)=900/x
x=900/tan(40)
x=1072.6
2. tan(37)=x/1000
1000tan(37)=x
753.6=x
3. sin(18)=60/x
x=60/sin(18)
x=194.2
4. sin(48)=x/80
80sin(48)=x
59.5=x
5. tan(22)=x/12000
12000tan(22)=x
4848.3=x
6. tan(33)=x/2800
2800tan(33)=x
1818.3=x
